It is common to see power figures taking center stage when discussing motorcycles when experienced motorcycle riders have listened to the full story. You cannot literally ride on a spec sheet but one parameter always suggests excitement in the real world: the power-to-weight ratio. This single test is a demonstration of the efficiency with which a motorcycle transforms engine power into forward force, which determines how fast, quick, and exciting it is on the open roads.

The importance of Power-to-Weight Ratio

• Acceleration feels in the real world
• Affects responsiveness and turning
• Trades between mass and engine output
• Modifies rider confidence
• Helps make comparisons between bikes in categories

The less weight per horsepower a bike has onboard, the more likely it is to jump up and down and swivel in its direction with a greater purpose. Other factors that affect the performance include comfort, suspension tuning and the rider skill, but this ratio provides a good baseline. It enables fans to draw comparisons between the machines in both segments and cost categories giving them a more accurate idea of which motorcycles in the real sense provide exhilarating performance.
